First thing to know, is that we are dealing with RTF format .doc files. - This is good news for us as it makes it easier for you to interpret than a binary file and means you can inspect the files using a raw text editor (eg. Notepad/Textpad/etc.) - If you have difficulty opening up the files, just change the extension from ".doc" to ".txt".
You might be able to copy and paste the following into your browser's address bar to view the original files as text too:

In all 3 documents, the following text string (a stylesheet definition) exists:
{ \s108\ql \li0\ri0\widctlpar\wrapdefault\aspalpha\aspnum\faauto\adjustright\rin0\lin0\itap0\contextualspace \rtlch\fcs1 \af1\afs20\alang1025 \ltrch\fcs0 \f1\fs20\lang1049\langfe1049\cgrid\langnp1049\langfenp1049 \sbasedon0 \snext108 \slink107 \sqformat \spriority1 \styrsid11758497 No Spacing;}
The fact that we find this in all 3 documents means that they all were based on the same document at some point. (It's the only logical explanation for all documents sharing this RSID (11758497) for starters and it's not the only RSID shared between the documents).
The "lang1049", "langfe1049", etc. parts of the string show that this is set to Russian language. (This may help: Microsoft Locale ID Values)
So we know that all 3 documents were based off an original document that already had a Russian breadcrumb associated with it even before the content in those 3 documents was present. It's probably something worth pondering over at the very least.
To clarify, if these were separate documents that had these specific "Russian-fingerprints" accidentally added while being handled - they would all have different RSIDs. - The only way for what we observe to have happened - is for all 3 files to have been based on a pre-tainted template.
In Spring 2018, the source of Flood's metadata was discovered and reported on here (the metadata came from a document originally authored by Flood in 2008 that was attached to Podesta's emails and that can be downloaded here).
A subset of the RSIDs on all three Guccifer 2 documents that had Flood's name on them can be traced back to the 2008 document and the metadata matches.
For further details on this and a lot more evidence discovered in relation to Guccifer 2, please read the final summary report.
